Exercise Metabolism and Bioenergetics

The study of energy in the human body

All of the chemical reactions that occur in the body to maintain itself.  The process in which nutrients are acquired, transported, used and dispose of by the body

The examination of bioenergetics as it relates to the unique physiologic changes and demands place on the body during exercise

The material or substance on which an enzyme acts

Organic compounds of carbon, hydrogen, and oxygen whic include starches, cellulose, and sugars and are an important source of energy.  Are eventually broken down in the body to glucose, a simple sugar.

A simple sugar manufactured by the body form carbohydrates, fat and to a lesser extent, protein which serves as the body's main source of fuel

The complex carbohydrate molecule used to store carbohydrates in the liver and muscle cells.  when carbohytrate energy is needed,  it is converted into glucose for use by the muscle cells.

On of the three main classed of foods and a source of energy in the body.  Help the body use some vitamins and keep the skin healthy.  Also serves as energy stores for the body.  Two types: saturated and unsaturated

The chemical of substrate form in which most fat exists in food as well as in the body

Amino acids linked by peptide bonds, which consist of carbon, hydrogen, nitrogen, oxygen and usually sulfur, and that have several essential biologic compounds

The formation of glucose from noncarbohydrate sources such as amino acids

Energy storage and transfer unit within the cells of the body

A high energy compound occurring in all cells from which adenosine triphosphate (ATP) is formed

The breakdown of triglycerides into smaller subunits called free fatty acids (FFAs) to convert FFAs into acyl-CoA molecules, which then are available to enter the Krebs cycle and ultimately lead to the production of additional ATP
